Background
Randomized controlled trials (RCT) are required to test relationships between physical activity and cognition in children, but these must be informed by exploratory studies. This study aimed to inform future RCT by: conducting practical utility and reliability studies to identify appropriate cognitive outcome measures; piloting an RCT of a 10 ...
Physical activity (PA) during childhood often occurs in social contexts. As such, children's ability to develop and maintain friendship groups may be important in understanding their PA.
This paper investigates the associations among children's social functioning, and physical activity and whether perceptions of social acceptance mediate any social functioning-PA association.

Background
Measuring physical at home and away from home is essential for assessing health and well-being, and could help design interventions to increase physical activity. Here, we describe how physical activity at home and away from home can be quantified by combining information from cellular network–based tracking devices and ...
Purpose
To assess the association between activity monitoring devices for estimating energy expenditure (EE) in the context of a home-based rehabilitation program.
Methods
Twenty four patients with abdominal aortic aneurysm (AAA) disease participating in a home-based rehabilitation program were studied. For 3 consecutive days (12 awake hours/day), subjects wore an accelerometer (...
Objective measurement of physical activity remains an important challenge. For wearable monitors such as accelerometer-based physical activity monitors, more accurate methods are needed to convert activity counts into energy expenditure (EE).
Purpose
The purpose of this study was to examine the accuracy of the refined Crouter 2-Regression Model (C2RM) ...
Background Accurate objective assessment of sedentary and physical activity behaviours during childhood is integral to the understanding of their relation to later health outcomes, as well as to documenting the frequency and distribution of physical activity within a population.
Purpose To calibrate the Actigraph GT1M accelerometer, using energy expenditure (...
Background
Low physical activity (PA) is linked to cancer and other diseases prevalent in racial/ethnic minorities and low-income populations. This study evaluated the PA questionnaire (PAQ) used in the Southern Cohort Community Study, a prospective investigation of health disparities between African-American and white adults.
Methods
The PAQ was administered ...
Introduction
Sedentary behavior (SB) is directly associated with a greater risk of death from cardiovascular problems, cancer and all causes. Moreover, SB is directly associated with obesity in children. This study examined whether there was a significant seasonal variation in objectively measured SB in Portuguese youth across five months of ...
Introduction
The PEACH project (Personal and Environmental Associations with Children’s Health: www.bris.ac.uk/enhs/peach) is a longitudinal study investigating the environmental and personal determinants of physical activity and eating behaviours in children across the transition from primary to secondary school. A cohort of 1307 final year primary ...
Background
Physical inactivity is a risk factor for obesity, cardiovascular disease, hypertension, and other chronic diseases that are increasingly prevalent in the U.S. and worldwide. Time at work represents a major portion of the day for employed people.
Purpose
To determine how employment status (full-time, part-time, or not employed) ...
